subsequent layer below. This enables the outer jacket, lead sheath or triple layer XLPE to be re-applied and the cable repaired. Even if the cable is just going to be scrapped, the metal price di erences for insulated or un-insulated cables are very large and the equipment would have a very short pay-back period, if the metals are scrapped in their ‘bright’ form.

➣➢➣ Today, there is a tendency towards testing of long submarine cables in one piece. Due to their high capacity, economical tests of submarine cables are not possible in the manufacturer’s factory. components and devices for the cable industry. One of the key strengths is the customisation of state-of-the art solutions. Highvolt is a pioneer in the development of mobile AC test systems with the most advanced applications for testing and diagnosis of extruded power cables after installation or repair on-site. The special design of resonant test systems with variable frequency ranging from 20 to 300Hz, type WRV, creates the conditions for real AC withstand tests on long cables after installation. Partial discharge tests including monitoring and diagnosis complete these tests. The modular application of these test systems, especially regarding power increase, allows real condition tests of cables with a length up to 100km and more. Presently, there are more than 100 of Highvolt’s mobile WRV test systems around the world.

install and maintain, fully automatic and extremely reliable with its state-of-the-art control system, enabling continuous operation for weeks with little or no variation in temperatures and wall thickness/concentricity. The lead wall thickness can be kept to a minimum with corresponding savings in lead. A range of die blocks are available to cover an extensive diameter range of 6mm to 225mm (over lead), and a range of melting pots are available for 10, 18, 35 and 60 tonne capacities. Additional equipment includes the cable repair and recovery system (CRRS), which has the possibility of removing individual layers, such as the outer jacket, lead sheath or triple layer XLPE insulation, without causing any damage to the
